SASH MOVER AND LOCK-- Specification of Letters Patent.

Application filed Apri14,1906. Serial No. 263.788.

To all whom it may concern.-

Be it known that we, ALFRED REGINALD HARDY, accountant, and ROBERT"NOBLE ADAMS, publisher, of Dunedin, New Zealand, have invented certainnew and useful Improvements in Sash Movers and Locks, of

. which the followin is a specification,

panying drawings, in which the same numerals of reference indicate thesame or similar parts, and in which' Figure 1 is a front elevation ofthe apparatus, the u per sash 18, lower sash 19, architrave 27 puley-stile 43, and facing-board 45 bein shown in dotted lines in order tomore clear y indicate the method of mounting the gearing and the meansof operating the gearing to enable the upper and lower sashes to beoperated independently or simultaneously. Fig. 2 is a side elevation ofthe apparatus, the

architrave being removed and a part of the upper sash 18 and lower sash19 being shown in section in 7 order to more clearly show how thegearing of the apparatus engages with the toothed racks 14 and15,secured to the side rails of said sashes'18 and 19. Fig. 3 is anenlarged view of a portion of Fig. 1 to show the method of actuating andlocking the gearing. When the handle 34 is removed,

4 as shown in dotted lines, the key 31 is in the position represented bydotted hnes. Fig. 4

1s a perspective view of the locking-plate 2 2.

of end ln s 4 7 and 6 9 carry short spindles 1 and 3, w 'le'the middleair carry the long spindle 2. On said spindles 1, 2, and 3 are mountedthe pinions 11, 12, and 13. The upper and lower pinions 11 and 13 arepreferab y of the same size and engage in racks 14 and 15, respectivelyattached to the side-rails 16 and 17 of the upper and. lower sashes 18and 19 of the window. To permit the pinions 11 and 13 to engage in theracks 14 and 15, clearance is provided in the pulley-stile 43 at 44. Themiddle pinion 12 is double the width of the other pinions 11 and 13 andis divided by a central flange 20, of greater diameter than the pinion12, said flange 20 being for e of engaging in a slot 21, formed thepuiggls in a 100 g-plate 22, (which locking-plate 22 is moreparticularly shown in Fig. 4.) Said locking-plate, which is ada ted toslide be tween the lugs 8 and 9 on t e face 23 of the base-plate 10, isprovided with projecting pieces 24 and 25, which are of ashape suit+able to engage in the s aces between the teeth of the pinions 1 1 an 13,for the purpose of locking either pinion to retain the correspondingsash in a fixed position when it is desired to operate the sashesindependently. The spindle 2, to which the pinion 12 is secured,isadapted to slide laterally in the lugs 8 and 5 and has its outer end 26projecting beyond the architrave 27. A slot 28 and a channel 29 areformed in said outer end 26 of said spindle 2, and said channel 29 isadapted to have a spiral spring 30 inserted therein. A key 31, havingone of its ends in the slot 28 and pivoted thereto, is adapted to lie inthe channel 29. .The spring 30 bears upward against the under face ofthe key, thus tending to force the key upwardly out of the channel. Alocking-washer 32, which has a central hole 33 and a slot 34 therein,communicating with said hole, is secured to the architrave 27, so thatits center is in line with the center of the spindle 2 in order that theend 26 of the spindle 2 may be revolved freely in the hole 33 by meansof the handle 34.- After the handle 34 is in the position illustrated inFig. 3 and the thumb-screw 35 is screwed home, securing said handle 34to the spindle 2, the apparatus is unlocked and. in a condition tooperate the sashes. Fig. 1 illu strates the apparatus a position wherebywhen the s indle 2 is revolved by turning the handle 34 neously to riseor fall, as desired according to the direction in which the handle 34 isturned.

To operate the uppersash 18 independently, (while the lower sash remainsin a fixed position,) the spindle 2, with its pinion 12 attachedthereto, is pushed inward until the and lower Window-sash having theiradjoinside 36 of the flange touches the face 37 of the pinion 11, thepinion 13 being thus disengaged from the pinion 12, and simultaneouslywith such disengagement the pinion 13 is en- 'gaged and prevented fromrevolving by the pro ecting piece on the locking-plate 22, therebylocking the lower sash 19, the said plate 22 having changed its positionowing to the flange 20 on the pinion 13 engaging in the slot 21 of thelocking-plate 22 and slidin along the face 23 of the base-plate 10 Witthe pinion 12. The turning of'the handle 34 thenoperates the' upper sashin the desired direction. When it is desired to operate the lower sash19 independently while the upper sash remains in a fixed position, acorre sponding 1process is followedviz., the spin dle 2, wit its pinion12 attached thereto, is withdrawn outward until the face 38 of theflange 20 touches the side 39 of the pinion 13,

whi e theprojecting piece 24 on the lockingplate 22 engages the pinion11, preventing it revolving and thereby locking the upper sash 18. Theturning of the handle then operates the lower sash in the desireddirection. When it is desired to preventthe sashes from being opened orclosed by hand, the spindle 2 is revolved until the key 31 is in linewith the slot 34*; The handle 34 is then removed, which permits the key31 under the influence of the spiral spring to enga e in the slot 34*,preventing the rotation o the spindle, and thus retaining the upper andlower sashes in a fixed position.

Having now described our'invention, What we claim as new, and desire tosecure by Letters Patent, is

1. A sash-fastener consisting of a baseplate having two pinions mountedthereon one at each end thereof, a larger pinion intermediate of the.outer two pinions mounted on a sliding spindle and divided into twoportions by a central flange each one of said portions being adapted tomesh with a pinion respectively, a slotted locking-plate for said flangeprovided with projecting pieces adapted to engage said two pinionsresectively, and means for rotatin and 100 'ng said sliding spindlesubstantia ly as and for i the purposes set forth.

2. A sash-fastener consisting of an upper the pinions 11 and 12 beingthus disengaged,-

ing side rails each provided with a rack, a pinion meshing with eachrack a middle pinion divided into two portions b a central flangemounted on a sliding spindlla, said portions being adapted to mesh withsaid two pinions res ectively, a slotted lockin -plate for said. piecesadapte 100 ng said sliding spindle, substantially, as and'for thepurposes set forth.

3. A sash-fastener consisting of racks secured to the sash, pinionsengaging'with said racks, a central pinion adapted to engage with thebeforementioned pinions to rotate the same, a sliding spindle for saidcentral pinion whereby said pinion may be moved out of engagement witheither one of the be- 'forementioned pinions and a locking-plate havin aslot therein in which a part of the centra pinion engages to move saidplate and projecting pieces'on said plate adapted to en age with thefirst-mentioned pinions to 100 the same against movement.

4. A sash-fastener consisting of racks secured to the sash, pinions 1113 en agin with said racks, a central pinion 12 adapted to engage withthe pinions 11 13 to rotate the same, a sliding spindle for the pinion'12 whereby said pinion may be moved out of engagement with either oneof the pinions 11 13, means for locking the pinions 11 13 againstmovement and means for preventing movement of the sliding pinion, saidmeans consisting of a key pivoted to the outer end of said spindle, saidspindle having a channel in said end in which said key fits, a spring insaid channel for forcing the key out of the channel, a washer having aslot therein and secured to the frame, said key engaging in said slotwhen forced out of the channel and a removable handle havin meansthereon for keeping the key in its 0 annel, substantially as described.

In testimony whereof we have signed our names to this specification inthe presence of two subscribin Witnesses.
